Imagine real world of invoicing. When you want to generate an invoice to a customer you have 2 possibilities with DueDate: or you write the Due days and the system calculates automatically the due date, or you enter the DueDate and the system calculates the due days.
So, in attached bsv we have a form where we select the Invoice Date suppose 02/21/2017, then we enter the duedays of 33, automatically the system puts DueDate=03/26/2017 (Correct)
If I enter 34 -> the system corrects and puts 33 and 03/26/207 (nothing works above 33 and 03/26/2017).
